1500--3000RMS, This has the same shorting sleeve as the vU, the magnets of the UHT are half the thickness of the vU, per Nathan and is where some of the savings come in. It's designed for HT where the vU would probably please a music only audiophile as well as a HT guy but at a much higher price.
I have a thread at AVS for the buy and Nathan has made a few posts there. We have 3 solid driver sales so if you have space for one let me know.
